Aluminum and aluminum alloy in modern engineering technology used in a variety of materials occupy a pivotal position, it in the world’s annual output is second only to steel and ranks the second, in the non-ferrous metal is the first. If aluminum alloy initially emerged in the aviation industry, then in recent decades, in addition to the aviation industry, in aerospace, automobiles, ships and even home decoration have been a large number of aluminum and aluminum alloy applications.
Aluminum alloy welding refers to the welding process of aluminum alloy materials. Because of its high strength and light quality, the main welding processes in the industry are manual TIG welding, automatic TIG welding and MIG welding. Among them, argon arc welding is the most widely used one. But with the development of the industry, the traditional argon arc welding in some fields has been unable to meet the increasing processing needs of users.
Traditional argon arc welding not only requires mature technicians, but also limited by the slow welding speed, welding difficulty, high ozone content produced during welding, harmful to human body; Due to the adverse factors such as large heat-affected area, easy deformation and difficult guarantee of weld quality, it has been subjected to many constraints in the development of the industry.
Laser welding is a kind of high energy density laser beam as a heat source, the material in a small area of local heating, the material after the formation of a specific molten pool to achieve the effect of welding.
In recent years, with the continuous progress of laser technology, the application of laser processing has become more and more broad, and the advantages are more and more obvious. Fast welding speed, high processing efficiency; No laser wire filling, reduce the cost; Reduce material deformation; Smooth and beautiful weld, reduce the subsequent grinding process.
